Toall whom it may concern:

"Be 'it 'known that 'I ,Jon 1\fso nS. "WAnerr, a citizenof the Unit'edSta-te's', residing'at Sheparch in the county"o;t' Franklin and Sensor Ohio, have invented a certain new d and useful Improvement in 'Fr'eight C'ar Door-s. of which the 'iollowin'g is" a specific'a tion. i l I This invention fen r I v lies niore'particularly to flush carfdoor's,"tliat is a shdmg door which when closed has; its outer er exposed side flush with the outer sin for the car. A variety of constructionsof such 'd'oo'rs have been proposed but so far as I aw'a're they have not gained very general approval and adoption because the supporting devices' a e. beseech. to qu too m ch.

projection beyond the sid'e ofthe ear; nd

have too much of their construction ex posed to the weather.

The object of my invention is to provide a construction which lessens the projection beyond the side of the ear and simplifies and compacts the structure and at the same time so far incloses it that the weather, particularly snowy, sleety Weather, can have no serious effect in interfering with or preventing the operation of the door at any time.

The invention is embodied in the example herein particularly shown and described and then pointed out in the claims.

In the accompanying drawings forming part hereof Figure 1 is a view in side elevation showing a portion of the side of a freight car equipped with a door and hanger according to my invention.

Fig. 2 is a horizontal sectional view on the line 00-00 Fig. 1 looking down.

Fig. 3 is a detail illustrating on a larger scale a swiveled trolley employed in the construction.

Fig. 4 is a detail section on the line v 4 Fig. 1 but on a larger scale.

Figs. 5 and 6 are detail views in horizontal section and plan view showing cams or guiding members on the car and door for forcing the door into closing or flush posi tion when the door is slid into place opposite the door opening.

In the views 6 designates the side of a car and 7 the door the latter having a handle 7 by which it may be moved. To'the upper edge of the side of the car in the corner under the cave of the roof is secured a strip "or" wood '8', and upon the outer face of this strip is 'secured'a metallic hood. The strip of 'metal'constituting this hood is made gen- "erally of two widths as seen at 9 and I0 and each portion has its lower edge bent inward toward the car to'forr'n tracks 9 and '10; The tracklm has'a continuation 10 in a "very iiarrow' portion that is curved toward the car and secured thereto. "The hood and track 9 are likewise curved toward the car.

These curved portions are so' formedthat a 'doorsupport'ed and slidable upon the tracks as hereinafter descr1loed-=1s directed toward the door opening or away therefrom according to the direction of force 'applie'd't'o' the The door is provided with suitable rollers i:lllziiidl? journ aled in oneleg'of J-sliaped frame carried by a plate adapted to be secured to the upper portion of the door. The J-shaped frame is adapted to embrace the lower edge of the hood including the track so as to keep the door on the track and aid in guiding it into and out of closing position. Either or both of the J-shaped frames can be swiveled to the securing plate as shown in Fig. 3. The lower edge of the door is guided and kept in position by suitable guiding members 14 and 15 secured to the side of the car near the lower corners of the doorway. The guiding member 15 is shown to have its operative portion more offset than that of member 14: for the purpose of providing room for the outward novement. of that portion of the door when the door is opened. A long linger 16 on the lower right hand corner of the door is provided to cooperate with this more. offset guiding member in forcing the lower portion of the door to closing position when closing movement is given to it.

A suitable latch can be provided for securing the door in closed position. The latch. shown consists of a sliding and rocking bolt 1.7 mounted in a plate 18 in the: door said bolt having a pendant loop 17 to embrace a staple 19 when the bolt has been thrown to engage a bolt catch 20 on the jamb or side of the car next the door opening. When the bolt has been manipulated to place it in latching position it can be there held by a pin 21 slid through the staple beyond the loop 17 of the bolt. To hold the bolt in iinlatched position the bolt receirin g plate or rrame 18 is provided with an intermediate projection 22, between which and said frame, the loop 17 falls and is held by gravity. 7

23 designates a stop on the side of the car to limit the opening movement of the door; and 24: designates a bracket to support the opened door in case it sags or to prevent its sagging on its hangers.

In practice, to open the door, the handle '7 is grasped and pulled outward from the car and to the right until open as far as desired, or until open as far as may be, as shown by broken lines Fig. 2. To close the door it is slid to the left, pressure being applied to carry it inward until flush with the side of the car. The hood imparts rigidity to the structure and prevents access of snow and ice to the tracks and trolleys to interfere with the operation of the door in the winter season;

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. In combination with a freight car having a door opening, a door, a supporting device for the door consisting of a hood so cured, near the eave of the car, said hood having two lower edges one above the other bent inward toward the car and constituting tracks independent of each other, said tracks having portions curved abruptly and substantially parallel toward the door and a roller for each track on the door to travel on said tracks. I

2. In combination with a freight car having a door opening, a door, a supporting device for the door consisting of a hood se cured near the eave of the car, said hood having lower edges one above the other bent inward toward the car and constituting tracks, said tracks also having portions abruptly and substantially parallelly curved toward the car, and a roller for each track on the door to travel on said tracks, said rollers each having a mounting adapted to embrace the under side of the track and the outer side of the hood.
